Sometimes we can recognize an FWH and SPI chip, but not the LPC item (but it's there).
The brand on the FWH is typically SST, Atmel, Intel or Winbond. However with the Winbond brand we'll have to be careful as they make many other types of chips too (not just memory chips - but their other chips typically have a lot of pins, ie. more than 32 for a FWH). The FWH is usually a 32-pin PLCC chip. Most/some of the time it'll be sitting in a socket so that it's removable if anybody wants to do this. It'll typically have a 29-something part number.
If we can't find a 32-pin FWH (PLCC chip with or without socket), then we'll have to look for an 8-pin chip of those similar brands. The part number is typically 25-something or 45-something, etc. The SPI chip is normally 8-pin, and it is sometimes found on recent motherboards using the Intel 965 or newer chipsets. It is normally soldered down - without a socket.
